Abstract:

Traditional medicines are currently the basis for much of the primary
health care delivered in tropical nations. Plant species endowed with
therapeutic properties, useful against human ailents, represent one of
the most powerful economic arguments in favour of maintaining the
world’s biological diversity. Aloe is well known for certain medicinal
properties, about 420 species have been identified globally. There are
6 species native to Rwanda, and it is widely used for treatment of skin
maladies and HIV/AIDS. In this study, we explored the antibacterial
activity and fungicidal activity of three varieties of Aloe native to
Rwanda, Aloe dawei, Aloe Volkenssi and Aloe sp. We compared
proteins extracted from these varieties and found significant differences
in protein content and medicinal properties. We found that the
Rwandan Aloe species studied possess antibacterial properties at
extract concentrations varying from 10-12.5 μg/ml against the majority
of Gram-positive and Gram-negative bacteria. However we did not
identify any antifungal properties. Our results suggest that Rwandan
Aloe is an effective antibacterial plant. More detailed studies of the
active properties of these species, as well as their diversity, distribution
and the conservation status are needed in Rwanda
